Discover our wide range of half-hardy annual seeds and plants, that will give you a magnificent display for your borders, containers or hanging baskets. 

Half-hardy annuals can be sown indoors or in a heated greenhouse to give them an early start, and brought outside once the risk of frost has passed.
